Android Studio　毎日指定時刻に動作を行う

前提・実現したいこと

Android Studioにて、ルーティン管理アプリを作成しています。データベースとしてRealmを使用しており、RoutineEditActivityで新しいルーティンの追加・編集・削除を行って、MainActivityに一覧表示しています。（ここまでは確認済み）

RoutineEditAcitivityにおいて、ユーザーがルーティンを行った場合はCheckBoxにチェックを入れます。日付が変わるごとにそのデータが保存され、5日分の記録を得点化したものを表示したいと思っています。

アプリ制作初心者であり、見苦しいコードであると思いますがご回答よろしくお願いします。

発生している問題・エラーメッセージ

日付が変わる際にRealmのデータを更新して得点の表示を変更したいのですが、エミュレータ上で変更作業が行われません。（アプリを実行することはできます。）
